This invention relates to display or advertising devices.

According to this invention such a device comprises a moving support which rotates at any prearranged speed at a given time, by means of which an article for sale or exhibition is displayed, and combined with this moving support are moving pictures which are descriptive of the article in question.

The moving support preferably has a rotary movement imparted to it so that different parts of an article on the supportare successively displayed to a spectator.

The moving picture may display a succession of advertisements of the article in the form of letterpress, descriptive diagrams, illustrations or advertisements, or a combination of any or all of these. The movements of the support for the article and of the moving picture are preferably synchronized in any suitable manner.

In place of the rotary movement described a rectilinear movement may be imparted to the support for the article or a combination of these two movements may be used.

The device preferably comprises a frame in which in addition to the article and the moving pictures other advertisements, which may be stationary or moving, are displaced.

In a convenient form of construction a series of different articles are successively displayed for any desired period of time on the moving support, a suitable moving picture applicable to each article being simultaneously displayed for a sim ilar period of time. The mechanism for successively displaying the articles may comprise an endless chain to which are secured a plurality of equidistantly spaced tray carriers.

A curtain may advantageously be dropped in front of the device during the interval of time that elapses between each display period.

It is to be understood that in the case of the moving chains the movement is a step by step one, and that there is an interval of time between the successive display of two articles.

Alternatively to displaying the actual article itself, such article may be represented in a variety of positions or stages of manufacture on a cinematograph film which is projected on to a screen and which is combined with the film previously described.

One form of construction of the invention is illustrated diagrammatically in the annexed drawings, in which:

Fig. l is a front elevation.

Fig. 2 is a sectional elevation, and

Fig. 3 is a plan.

As shown, the apparatus comprises a plurality of carriers a, mounted on an endless chain b, 69 which passes over a number of guide rollers 0. Each carrier a is provided with a rotary support (2 for the article to be displayed. Teeth c are mounted on the lower surface of each support (1, and the teeth on each support are engaged successively by a toothed spindle I, provided with a driving gear 9 and a solenoid h by means of which the spindle i may be periodically withdrawn against the action of a spring h. The whole apparatus is mounted within or behind a frame j which is provided with a display opening is, in front of which each carrier a is in its turn held stationary for a predetermined period. This opening k, which may have a screen k is normally covered by a movable curtain Z which is automatically raised and lowered in synchronism with the movements of the chain b by means of a chain m that passes over the guide rollers n.

There is also provided a cinematograph projector o driven in synchronism with the carriers (1, the film a: as it is unwound passing over the rollers p and finally returning to the projector in such manner that it is ready to be displayed again, the film being displayed on a screen 1 It may under certain conditions be undesirable to mount the articles on the rotary supports 11, and in such cases the articles are displayed on a glass screen, which may be suitably illuminated, and which is mounted beneath each support. In such cases the support d will be removed by unscrewing a nut q and releasing a bolt r.

Having thus described the nature of the said invention and the best means I know of carrying the same into practical 'efiect, I claim:

In a device of the kind described, endless supporting means having an intermittent movement, carriers pivotally supported by said endless supporting means and each carrier having an opening therein, rotary platforms in the carriers having gear teeth adjacent the openings, a springprojected pinion for entering the opening and engaging the gear teeth, means for rotating said pinion, and a solenoid for withdrawing said pinion from engagement with the teeth and out of the opening of the carrier against the influence of the spring.
